( Figs 27G–L )

Dorilas (Eudorylas) natalensis Hardy 1949 a: 45 .

Diagnosis: Surstyli's angled tips point towards each other; ST8 enlarged, almost divided by m.a.; gonopods asymmetrical, OG with hairs; phallic guide pointed (also curved in lateral view) and hidden by band-like structure (not membranous); phallus trifid, branches thick; ejaculatory apodeme linear with a swollen “bulb”; sperm pump round with depression in the middle.

Type material: South Africa: 1♂, HT, Durban , Natal, Africa, [other side of the same label:] 4457 ( AMNH) .

Male

Head. Third antennal segment acuminate; brown-black. Face silvery pollinose. Frons, upper part subshining black, lower part black pollinose with shiny spot in the middle; eyes touching for distance equal to 4 times ocellar triangle. Occiput, lower half silvery pollinose, upper half brownish.

Thorax. Humeri black. Mesonotum (viewed obliquely from front) brownish pollinose; also from the side and scutellum, latter without hairs. Dorsocentral hairs weakly developed. Halter black.

Legs. Completely black, f3 shining posteriorly. Ventroapical row of 4 very short black spines on f1, no spines on f2; 3–4 longer pale spines on 3rd femur. Subapical (distal) spines on first four tibiae absent. No anteromedial hairs on 3rd tibia. Hind trochanter without hairs or spines on ventral side. Pulvilli shorter than last tarsal segment.

Wing. Cross-vein R-M at 1/3 of discal cell. Pterostigma fully coloured. Hairs on tegula absent.

Abdomen. Tergites completely brownish pollinose. No hairs, 2–3 lateral bristles on first tergite. Postabdomen in dorsal view: T5 as long as ST8. Genitalia without dissection: m.a. as wide as width of ST8, pv directed.

Genitalia. Surstyli's angled tips point towards each other; epandrium short, rather wide; ST8 enlarged, almost divided by m.a. ( Fig. 27H ). SES not developed; gonopods asymmetrical, OG with hairs; hypandrium with enlarged lobes; phallic guide pointed (also curved in lateral view, ( Fig. 27G )) and hidden by band-like structure (not membranous) ( Fig. 27J ); phallus trifid, branches thick; ejaculatory apodeme linear with a swollen “bulb”; sperm pump round with depression in the middle ( Fig. 27L ).
